Abstract

A microchamber array includes: a first substrate; a second substrate facing the first substrate; a flow channel provided between the first substrate and the second substrate and through which a solvent containing a sample flows; a chamber body, which is provided on a surface of the first substrate and which faces the second substrate; and a plurality of storage parts provided in the chamber body. Further, the first substrate has a recess recessed from the surface of the first substrate in a thickness direction of the first substrate at a position overlapping each of the storage parts.

Claims (24)

1 . A microchamber array comprising:

a first substrate;

a second substrate facing the first substrate;

a flow channel provided between the first substrate and the second substrate and through which a solvent containing a sample flows;

a chamber body, which is provided on a surface of the first substrate and which faces the second substrate; and

a plurality of storage parts provided in the chamber body, wherein

the first substrate has a recess recessed from the surface of the first substrate in a thickness direction of the first substrate at a position overlapping each of the storage parts.

2 . The microchamber array according to claim 1 , wherein

the chamber body includes a water-repellent resin layer and a light-shielding resin layer, and

the light-shielding resin layer and the water-repellent resin layer are stacked in order on the first substrate.

3 . A method for manufacturing a microchamber array, comprising:

forming a chamber body on a first substrate;

forming a plurality of storage parts in the chamber body; and

glass etching a bottom surface of each of the storage parts with a cleaning solution after the forming of the storage parts.

4 . A method for manufacturing a microchamber array, comprising:

forming a light-shielding resin layer on a first substrate;

forming a plurality of first openings in the light-shielding resin layer;

stacking a water-repellent resin layer on the light-shielding resin layer;

forming second openings at positions overlapping the respective first openings in the water-repellent resin layer; and

glass etching a bottom surface of each of the first openings with a cleaning solution after the forming of the first openings and the second openings.

5 . The method for manufacturing a microchamber array according to claim 3 , wherein the cleaning solution is dilute hydrofluoric acid.

6 . The method for manufacturing a microchamber array according to claim 4 , wherein the cleaning solution is dilute hydrofluoric acid.

7 . The method for manufacturing a microchamber array according to claim 3 , wherein the cleaning solution is at least one of Semico Clean 56, GC-3022 FT, PK-LCG series, SUNECON AS-3, and Semiclean series.

8 . The method for manufacturing a microchamber array according to claim 4 , wherein the cleaning solution is at least one of Semico Clean 56, GC-3022 FT, PK-LCG series, SUNECON AS-3, and Semiclean series.
